Abstract

A transport device for a sheet-format substrate has at least one first substrate feed device and has at least one second substrate feed device. The at least one second substrate feed device comprises at least one forward stop and at least one singulating device. At least one substrate guiding device is arranged between the at least one first substrate feed device and the at least one second substrate feed device. The at least one substrate guiding device has at least one directing element. The at least one directing element is mounted such that it is movable or is moved in two different directions independently of one another.
